Question

Urgeeeente por favor preciso da C, E e F.

Answer 1

a)

A=(10+24)*12/6

b)

12,5²=h²+10² ==>h² =56,25  .h=7,5

A= (5+15)*7,5/2

c)

A=(4+10)*5/2

d)

15²=9²+h² ==>h²=144 ==>h=12

A=(20 +20+18)*12/2

e)

(2√10)²=h²+4  ==>h²=40-4 ==>h=6

(6√2)²=6²+x² ==>72-36=x² ==>x=6

A=(6+2+6+6)*6/2

f)

sen 60=h/4√3 ==>h= 4√3 *√3/2 =h  ==>h=6

cos 60 =x/6 ==>x=3

tang 45=6/y ==>y=6

A=(6+6+3+6)*6/2
